[Q & A] help Xiaomi Mi 8 won't boot

Firstly I want to thank every one here
I want to clarify for the first that the phone was already unlocked when I bought it. All go well until the day of doing this stupidity
I put the version 8.9.20 it got stuck (this miui version can't be installed on this device __1st attachment) but when I wanted to return to 10.0.20 with fastboot it tells me locked phone I managed to update to 8.10.25 with another tool but I was still stuck with this screen (1st attachment)
So I thought I need to unlock it I launch the unlocking tool he announces this message (current account is not bound to this device __2nd attachment)
Conclusion phone that has not done yet a month with totally unusable I was so happy with this phone that I could not return to iPhone.
Please find me a solution dear friends
My mi account id is 144253908
My Device is Xiaomi Mi 8 Global version bought from Gearbest
Do you have an unlocked bootloader? Flashing different rom, like you had installed on your phone (global, xiaomi.eu) need unlocked bootloader and twrp recovery. Or, if you had opened bootloader, and you flashed with Mitool, then you should unmark befor flashing the flash and lock option, cos ist closing your bootloader and bricking your device. Also have the last time xiaomi devices antirollback. For more info have a look in forum!Its already thread about this!
Can i resolve this problem with edl xiaomi cable ?

I see a lot of people with bricked devices, what precautions should I take?

I see a lot of people with system has been destroyed error messages, both here and on reddit. Tomorrow will be 7 days since I bought the phone and I will be able to unlock the bootloader and I'm planning to flash twrp and xiaomi.eu.
I have the global mi 9t version bought from Europe with stock miui 10.3.3. Can you please recommend me some precautions to take to avoid bricking my device? I rooted a lot of devices over the years and I only had problems with my girlfriend's Mi A1 which I bricked and had to send to a service repair. So I'm a bit nervous with xiaomi phones and especially this device since I see so many problems. Is there a specific guice for this phone Mi9t pro, or is the k20 pro guide good?

Almost all of these problems have been caused by people flashing fastboot ROMs with the Mi Flash Tool, where the ROM is for a different region to the phone. The problem happens when the default flash option of 'clean all and lock' has been used. Doing this is what causes the device to brick. Sometimes this has been done deliberately because the user didn't realise that it would brick and was trying to enable financial apps or Netflix, etc. to work correctly. Most of the time it's because the user hasn't been paying attention to what they are doing and forgot to change the flash option.
The only precaution you need to make, above and beyond what you would do for any other phone, is to check and double check, then check again that, whenever your flashing in the Mi Flash Tool, before you hit the Flash button you have changed the flash option at the bottom of the screen to 'clean all'.
If you actually do want to lock the bootloader then check, double check, then check again that the fastboot ROM you're installing is definitely, 100% the correct region for your phone.

I never used the MI flash tool, tomorrow I will use it for the first time to unlock the bootloader and the rest of the process I will do through fastboot commands. I hope everything will be fine thanks

Tomorrow you'll be using the Mi Unlock Tool.
A couple of things to point out. There is an issue with some/all versions of TWRP (not sure if they are all broken), - fastboot boot TWRP.img doesn't work, you'll end up having to reinstall a ROM if you try it, so use another method to boot into TWRP.
If you ever consider relocking the bootloader, then the standard fastboot command to do this won't work, I cannot remember if this will brick the phone or not.

I have the same concerns for my new mi9t pro.
Here is an article to read about anti rollback https://www.xda-developers.com/xiaomi-anti-rollback-protection-brick-phone/ to realize why there are all that problems and a method to see the indexes of the device and the ROM in order to make the right decision if it is safe flashing a specific ROM or not.
I don't suggest to consider K20 PRO cases familiar with the mi 9t pro, cause they have their own ROM versions specifically for China and India and that's is a part of the whole XIAOMI's anti rollback strategy.

Is there a problem with the mi9t pro global rom?
Planning to flash it on the k20 pro
That way you change MIUI region versions. That is the reason XIAOMI uses anti roll protection.
BECAREFULL. You must check the indexes of your device and the GLOBAL ROM you wanna flash

I have Chinese k20 pro and ibe flashed both eu roms and now im on global stable PIe (from android 10).
Bro just dont re lock your bootloader if you not have the official rom. Chinese or global.
If your phone is china you can relock the BL only if you flash china stock firmware.. the same you can do if your phone is global (mi9t pro).

I suppose now you can't go back because your phone's index is updated, so if you flash older ROM u will brick the device ?

Recovering from botched MIUI 11 OTA on fake Global ROM Mi 9T Pro?

I ordered a "Global ROM Xiaomi Redmi K20 Pro 12GB 512GB Exclusive Edition Smartphone Snapdragon 855 plus 4000mAh 48MP Triple Cameras 6.39'' on AliExpress (yes I know now it was mistake to get "Global ROM"...). Everything actually looked really good, Google Play store worked, device model showed up as "Mi 9T Pro", only thing I needed to do was lock bootloader for banking apps etc and everything has been working great.
At some point I was offered OTA update to MIUI 11, and I decided to install it last night. The install went until 65% and then the screen went black and the phone rebooted into the dreaded "The system has been destroyed" error. Now since my bootloader is locked I don't know how to recover from this - Mi Unlock Tool and fastboot both won't unlock, Mi tool wants me to add my account in developer options which of course isn't possible. I tried the "fastboot continue" method too with no effect. All I want is stock MIUI with locked bootloader and working OTA updates.
fastboot vars:
product: raphael
secure:yes
anti:1
board_version:4.9.2
hw-revision:20002
unlocked:no
Is EDL mode the only way to recover from this?
So you locked your bootloader and installed the OTA?
Unfortunately yes, bootloader was locked when OTA was installed.

Flash correct regional ROM through QPST/QFIL
You'll get a locked bootloader with OTA updates
Thanks for the response. It looks like QPST/QFIL only work if the device is already in EDL mode. Is there a way to boot to EDL without special cable / using motherboard test points? I tried fastboot oem edl and got "FAILED (remote: 'Oem edl command is not allowed Lock State')".
Following this Thread. Let me know If you get any Answer please mine stuck too and cant do aything and dont want to open my brand new device.

It doesn't work with Raphael.
So an update for those wondering. To fix this I had to use EDL mode and flash the original China ROM. It seems EDL cables do not work on this phone, so I had to open it up and use the test point method to boot into EDL mode. Even in EDL mode and using QFIL, there is still an authentication process on the phone itself, which requires an authorized Xiaomi account in order to load firmware. Obviously my own account does not have that authorization, so I paid $30 to one of those shady looking "unbrick" services. They remoted into my PC with UltraViewer (TeamViewer ripoff) and logged into their account and the flash succeeded.
Lesson learned... never lock the bootloader on this phone!

Brick MI 9 fastboot bootloader, locked bootloader until This MIUI version can not installed in this device

Hi Guys, I experienced fastboot bootloop in my Mi 9. Since the product not officially release in my country, the Xiaomi center refuse to check and repair it. So i did googling and did some test from flashing global ROM to unlock bootloader and ended with This MIUI version could not installed in this device.. But it all not working. I couldn't get the COM connection to the device. Any suggestion?

Xiaomi Mi 9T Pro Bootlooder locked

Hi Guys,
I purchsed Xiaomi Mi 9T Pro from Aliexpress with a Global Rom version but the device is a Chinese version.
The seller had to install global firmware and assosiate my device to other Mi account.
The current situation is my bootloader is locked and I can not use the Mi officially to unlock my device.
I tried to contact to the seller, but he can not assist me (they don't know the Mi account access details to release my device).
Duo to that, I tried looking the internet and found this forum. I have a good technic skill so I start tested all the suggestion the forum has to offer.
First I tried ADB and Fastboot, both are failed with the error - FAILED (remote: Token Verify Failed, Reboot the device)
I also tried miflash but he's requesting Mi account that I dont have the device their. I tried to flash a new fastboot but no success.
I really dont know what else to try, I hope someone here can spred some light on my issue from stoping my device to use as doorstops.
Thank you,

The bootloader cannot be locked to a Chinese device with a Global rom.
There is no Chinese Mi 9 t pro, the Chinese version is the K20 pro.
What is the phone model (my phone/characteristics/model)?

The device stuck on "Main Menu" MIUI Recovery 5.0 so I can not verified the phone model, but according to the seller page the model is: M1903F11A
https://www.aliexpress.com/item/33016509936.html?spm=a2g0o.order_list.order_list_main.61.21ef180253I770
I also tried to use MTK to unlocked the bootloader but I had no success to get the device into a brom mode. I can not trun the phone off, Vol+ & Vol- not works.
Is there any difference between the Mi 9 t pro and the K20 pro?
According to the model number, it is a K20 pro.
Chinese device so the bootloader is locked but with a Chinese rom since this is not possible with a global rom.
Same device except less 4G bands for the K20.
ok this is a start, any advice how to unlock the bootloader?

If the device is linked to an account that is not yours, nothing to do.
Is it a new or used device?
Check with the seller or send the phone back to him.
The device was new when I purchased it, the seller said there is no warranty on the device and he can not do anything about it. they used outsource company to do the installation of the Global ROM.
Surely there is a way to bypass Xiaomi locked on the bootloader. the Kernel can be overwrite somehow. just need to find the right way.

This model is from 2019, seems strange that Ali sells new ones.
And you still don't understand that there can't be a Global rom on this model with the bootloader locked.
The bootloader was not locked when I purchsed the device...

What you are saying now is inconsistent with your original post.
A long story to get to 'lock with fastboot'.
I'm sorry if there was a misunderstanding, here is the long story:
In 2019 I got this device from Aliexpress with a Global Rom version but the device is a Chinese version.
The phone was in English, working well with Google Play, and there was no issues with it.
In few months ago I wanted to start using Google Pay and my credit card was not approved for some reason, I contact google suppport and one of thier questions was "Have you unlocked your bootloader, rooted your device, or installed a custom ROM?"
So I started to google it, I find that my bootloader is unlocked, so I thought that I will need to lock it to be able using the Google pay service. what was found a terrible mistake.
First I understand that the only legal way to unlock it was using the Xiaomi official Mi program to unlock it. what I was found that I need Mi account with a registered device on it. my device is registered on some Chinese guy that I dont know so basically he's the legal owner of my device. so I start to look for an alternative solutions.
In my knolage with programs, I can handle with complex solutions to bypass this issue. but none of my trying wasn't succeeded. as I mentions I tried many was to bypass Xiaomi servers, now I found Miracle Box that promising to do the trick but its for only registered members. also there are some guys that said they can unlock the bootloader for money, but I dont know how trust they are....
I hope some of you guys can lead me to any idea/solution or something....
Thank you all for your time, much appriciated.

So, since 2019 you have used your device without a Xiaomi account, which severely limits Xiaomi services?
never used Xiaomi services...
Try to erase the data with the recovery or safe mode, if the option exists, but anyway if the phone is linked to an account you will be asked for the password.
Accounts are linked with a phone and email number and when you change the number a message is displayed.
Thank you, already tried it...
Is anyone know somthing about this? https://github.com/Canny1913/miunlock
Is the token is the key to success?
To sum up:
You have bricked your phone by locking the bootloader with a Global rom.
The reboot is possible but paying but when the phone reboots Xiaomi will ask you for your account and password.
Never ending Story.

Users who want to flash their phones need to study how to use tools, which ROMs to flash, etc
Eg, when flashing a ROM by Mi Flash, always uncheck relocking of the Bootloader. Then, if anything goes wrong, Bootloader will remain unlocked and one can still flash another ROM to easily unbrick the phone
